Replaces .bib file in output directory

[cristinasparks]

If the output directory is the same as the input directory, and the .bib file is in that directory, running the package will remove the .bib file

MS review:

Test 1: Scanned 10 publications related to the topic "windpower":

• 7/10 properly downloaded
• 3 are PDF, 4 are non-PDF
• Out of the 3 not successfully downloaded, two come from IEEE LATIN AMERICA TRANSACTIONS, one from INTERNATIONAL JOURNAL OF RENEWABLE ENERGY RESEARCH.
• One document downloaded file has no file name - called pdf.
• CSV looks like the output in R

Test 2: Scanned 10 publications related to the topic "drones conservation:

• 9/10 successfully downloaded
• 1 not successfully downloaded is derived from EUROPEAN RESEARCH CONSORTIUM INFORMATICS & MATHEMATICS. This pdf not easily accessible (not on google scholar)
• All chrome documents
• CSV looks like the output in R

Test 3: Scanned 10 publications related to the topic of "Yellowstone National Park":

• 9/10 successfully downloaded
• 1 not successfully downloaded is derived from JOURNAL OF PARK AND RECREATION ADMINISTRATION.
• None of the downloaded publications are pdfs - all are chrome links, most open a blank web page.
  • CSV looks like the output in R

When the input bib file is stored in the "outdir" folder, all previous input files, including the bib file used to perform the download, are overwritten by the output files. Should fix or may consider placing a check to ensure input bib files and R outputs are kept separate.

If you remove line 117 crminer::crm_cache$delete_all() the .bib file stays in the folder, however it also leaves a weird unopenable .pdf in the folder. Working on figuring this out

• If you repeat this process (with all the original files from the previous run), it crashes everything and creates 5-6 unopenable pdf files. It also deletes the .bib file.
